BALE-COMPRESS.,

SPECIFICATION forming part of Letters Patent No. 402,636, dated May 7, 1889. Applioationled June 19, 1888. Serial No. 277,575. (No model.) Y

.To all whom it may concern.: Y

Beit known that I, SAMUEL J'. WEBB, a citizen of the United States, residing at Minden, in the parish of Webster, State of Louisiana, have invented certain new and usefull Improvements in Bale-Compresses, of which the following is -a specification, reference being hadtherein to the accompanying drawings.

This invention has relation to bale-compresses, and the objects and advantages thereof will be hereinafter described, and the novel features will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a front elevation of a bale-compress constructed in accordance with my invention, and Fig. 2

detail view of the exhaust-valve 13.

Like numerals indicate like parte in all the gures. Y v 1 represents the cross-head of the compress, which is of the usual construction and is supported in position by the four opposite risers 2, the lower ends of which pass through the base, the structure being bound together by suitable nuts applied to the ends of the Bolted to the base 3 is a steam-cylinder, 4, the bottom of the same being formed by said base. 'Lugs 5 are formed upon the outersurface of the cylinder near its top, which embrace each of the risers and serve to maintain the cylinder in position while under pressure.V An annular ring, 6, is bolted to the top of the cylinder and forms the head thereof, and in the opening in the ring is seated a sliding smaller cylinder, 7,- open at both ends and provided with lateral flanges 8 and 9 at its upper and lower ends, respectively.

vThe iianges 8 and 9 are for the purpose of limiting the movement of the cylinder 7,.and they-extend inwardly in order to engage with the head 12 in its up-and-down movement.

Fig. 3 is aV is reduced at its lower end and provided with the piston-head 11, designed to iit the larger cylinder, 11, and with the smaller head, 12, at its center, which lits and operates in the smaller cylinder, 7. The reduced lower end of the rod 10 extends below the under surface of the piston-head 11 and terminates in a valve adapted to open and close a steamexhaust, 13, formed in the base 3, to which a suitable exhaust-pipe is attached. The details of this valve are shown in Fig. 3, the valve being removed in Fig. 1 to show the exhaust-opening. An opening,13x, is formed in the lower end of the cylinder 4, through ,y

which steam is supplied. The reduced stem portion 13 of the piston-rod 10 performs another function other than the regulation of the exhaust, in that it 'prevents the pistonhead 11 from coming in contact with the base 3, whereby a steam-space is formed between f the head and base, thus forming a cushion of steam.

Mounted for movement between the vertical risers 2 and above the cylinders i and 7 is the hydraulic plate 14, which plate is supported in position and actuated in its movement by a system of toggle-levers pivoted to the plate and to the smaller head, 12. This system is duplicated at each side of the hydraulic` plate, and consists of the opposite members or sections, 15 and 16, the upper members, 15, beingpivoted to therplate by means of pins 19, passing through the ends of the plate and the sections and forming a kneejoint, as at 18, with the lower members or sections, the ends of which are pivotally connected, as at 19X, to the piston-rod 10. From the pin 18 of eachpair or systemcf levers there extends a central section or lever, 20, the outer end of which is pivoted to the bearing-pinv21, journaled in the opposite risers 2 at each side of the frame-work. The framework is strengthened and prevented from spreading at this point by suitable tie-rods, 22, which are passed through the riser, embracing yolie 23 at each side ofthe said framework.

The `hydraulic plate is centrally and vertically bored, as at 25, and provided with a cylinder, 26, the upper end of which extends bethe upper' head, 27, of the piston-rod 10, which serves as a hydraulic plunger. An annular recess, 24, is also formed in the plate 14 and surrounds the cylinder 26.

Above the plate is mounted the movable platen or follower 28, at each of the four corners of which are formed riserembracing lugs 29. At the center of the platen there is formed a depending head, 3l, which, when the to platen is in its lowermost position, depends slightly into the top of the cylinder 2G. An annular flange, 30, also depends from said plate, fitting into the recess or chamber 24, formed in lthe plate 14, the outer surface of said flange forming a water-tight and sliding joint with the Wall of said chamber and form ing a Water-space between the inner walls of said flange and the cylinder 26.

The operation of my invention is as follows: 2o The steam-supply valve being opened, the steam is admitted through the opening 13X, under the piston-head 11, which ascends and carries with it the smaller head, 12, which, through the medium of the toggle-levers de- 2 5 scribed, raises the hydraulic plate and platen and carries the bale up against the head of the press. As the head 12 ascends, it comes in contact with the flange 8, formed on the cylinder 7, and raises said cylinder until 3o the head 27 of piston 10 comes in contact with the projection 31 of the platen. At the time that the smaller cylinder, 7, is being lifted the hydraulic plunger 27 is moving for- Ward and forcing the water contained in the 3 5 cylinder 26 out into the chamber 24, whereby the bale is hydraulically compressed. The exhaust-valve is now opened and the parts resume their normal position.

By this construction it will be seen that the lo compress is greatly simplified, and that al1 strain occurs between the cross-head 1 and the point where the levers are pivoted to the iisers, and that the strain is in a direct vertical line, and that the employment of a base is obviated.
